Soles: Soles by Michelin: Inspired by Michelin motorsport tyres, the specially developed non-staining rubber compound with integrated directional tread ensures maximum control – in every situation. Re-Action Zone: Secure grip during fast changes of direction and dynamic turning movements. The Re-Action Zone was developed to give you the best possible support during agile and explosive movements. Ergonomic Shape: The heel area of the shoe is adapted to the natural rolling motion of your feet and transfers your power to the ground perfectly. Protection Zone: The Protection Zone in the forefoot area protects you and your shoe and therefore enhances the adhesion. In addition, it offers you a secure grip on the ground even in an extreme incline position. Midsole: KOURTFLY TORSION: More stability with every step. Our torsion system specifically stabilizes your rearfoot and midfoot, effectively protecting against lateral rolling thanks to the smart combination of arch support and anatomically shaped midsole. K-PWR: Maximum power thanks to K-PWR. The midsole’s unique shape absorbs the acting forces and optimally transfers them to the outsole. This gives you a secure fit, the highest possible energy return and perfect stability.The particularly responsive and high-performance foam is made of 100% EVA, 20% of which is derived from recycled materials. ORTHOLITE®: Maximum rebound, breathable comfort, and sustainable materials – the removable OrthoLite® X40™ insole provides noticeable support with every movement. Upper: Ultra-Light Breath-Mesh: The lightweight and breathable upper material guarantees a natural feel, ensures efficient moisture transport from the inside to the outside and provides maximum comfort. Microfiber Reinforcement: The upper material features microfiber reinforcement in the midfoot, heel and toe areas, providing you with secure support during powerful and fast movements. DYNAMIC SOFT FIT 2.0: Flexible 3D knit with high elasticity – for a smooth, adaptive fit that moves with you without compromising support. HEEL LOCK: Special grip material in the heel area securely locks the foot in place – for a firm fit and greater control with every movement.
